3 Claims.

This vinvention relates to a fiat iron designed and adapted for steaming and pressing fabric and other closely analogous materials.

Some of the objects and advantages of the invention are as follows. The iron is capable of generating steam in kind and quantity steadily even though a steaming and pressing operation is carried out constantly over a comparatively long period of time.v 'I'here is present by virtue of the construction of the iron an improved distribution of the water for generation into steam, while at the same time keeping the pressing surface of the iron from becoming overheated thereby eliminating scorching of the material being ironed. There are provided primary and secondary steam generating means and Aprimary and secondary steam expansion and superheating means wherein steam may be confined and from which it may be released for distribution to the material to be steamed and/or pressed.

Fig. 6 is a diagrammatic view illustrating the various Water and steam generating passages, steam expansion chambers, steam distributing passages and connections between they same, it being vunderstood that .some of the connections are exaggerated due to the nature of the illustration.

In accordance with the invention the pressing and steaming iron I includes a Weighted body II. The body II consists of a base or lower steaming and pressing section I2, an upper steam generating and steam expansion and storing section I3 and a top enclosing section I4. The sections I2, I3 and I4 are held in assembled body forming relation by screw bolts I and sections I2 and I3 are further secured to each other by a screw IS. The body II is heated by means of an electric heating element I1 of any suitable well-known form, the heating element being held in place between the sections I2 and I3. In the lower section I2 there is a conduit means or passage I8 consisting of V-shaped branches 20, respectively, which are interconnected, the branch I9 lying within the branch 20 in the rear portion of the section I2, as shown most clearly in Fig. 3. 'This conduit means or passage I8 has an inlet 2| in continuation of the branch I9 and an outlet 22 incontinuation of the branch 20. The water to bel generated into steam is fed to `the passage I8 through a'. coil of tubing 23 which is connected with the inlet 2| by means of a nipple 24. The coil 23 serves as a means for preheating the water. The passage I8 constitutes a primary steam generating means below the heating element I'I. This primary steam generating means is connected with a secondary steam generating means in the upper section I3 of the body.

The secondary steamgenerating means consists of a conduit or passage 25 which extends along the marginal edge portion of the section I3 throughout and lends in a forwardly extending outlet portion 28, shown most clearly in Fig. 4. 'I'he outlet 22 of the passage I8 is connected with the inlet 21 of the passage 25 by a tube 23 and suitable couplings 29 and 30, respectively, constituting parts of the connection between the passages I8 and 25 exteriorly of the body il. The inlet 2'! extends upwardly through a boss on the section I3. The passage 25 is in the bottom portion of the section I3 and, therefore, lies directly above the heating element I There are formed in the upper section I3 a rst steam chamber 3| and a second steam chamber 32 above the passage 25. The steam y chambers 3| and 32 extend substantially throughout the section I3 in the same plane. The chamber 3l extends around the chamber 32 except at the rear thereof. The outlet portion 26 of the passage 25 communicates with the Vchamber 3l by a port 33 in the bottom wall of the chamber 3|.A The section I3 has an enlargement 34 formed integral therewithand there is an upow duct 35 in the enlargement 34 I9 and which communicates with the chamber 3i at the rear and at one side of the section I3, and there is also a downow duct 36 in the enlargement 34 which communicates with the chamber 32, as

shown most clearly in Figs. 1 and y(i.

In order to control the ow of steam from the chamber 3l to the chamber 32, there is provided a manually operable valve 31 bolted to the en-v largement 34 by bolts 38. This valve has ducts 39 and 40 therein which communicate with the ducts 35 and 36, respectively. The ducts 39 and 40 communicate with a passage 4I in the valve casing. This passage 4l is controlled by a spring-actuated valve member 42 actuated by a hand lever 43 of the valve. By pressing down on the lever 43, steam will flow from the chamber 3l through ducts 35 and 39, passage 40 and ducts 40 and 36 into the chamber 32. When pressure on the lever 43 is, released 'the valve member 42 will be moved automatically to its seat to close the passage 4l and thereby shut off the flow of steam.

The lower section l2 of the body Il has an A- shaped steam passage 44` therein lying in the plane of the passage I8 and the pointed end extending forwardly, as shown most clearly in Figs. 3 and 6. Portions of the passage 44 have discharge orices 45 which open through the pressing surface of the base '|2. The section I3 hasv a port 46 therein which establishes communication between the chamber 32 and a duct 41 bored in the screw I6. The duct 41 at the lower end communicates with the cross portion of the passage 44, as appears most clearly in Figs. 1 and 6. It will therefore be understood that when the valve 31 is open steam may ow through the same from the chamber 3l to the chamber 32 and from the chamber 32 through ducts 46 and 41 into the passage 44 and out through the orifices 45. In this manner steam is delivered to the material to be steamed and pressed by the iron manipulated by the handle 48 secured to the bolts l5.

I claim:

1. A flat iron for steaming and pressing including a body consisting of a, lower and an upper section, the lower section having a pressing surface, primary conduit means in said lower section to receive water for generation into steam, secondary conduit means in the upper section for continuing the generation of steam, a connection between the primary and secondary conduit means, primary and'secondary steam eX- pansion chambers in said Vupper section communicating with said secondary conduit means, heating means to heat said sections, passages in the lower section opening through said pressing surface and communicating with said secondary steam expansion chamber, and means to control the ow of steam from the primary to the secondary steam expansion chamber in order that steam may ow into said passages.

2. In a steaming and pressing iron, a body consisting of a base section and an upper section, heating means arranged between said sections to heat the same, a steam generating passage extending in said base section only at the rear portion thereof and having an inlet and outlet at the rear of the iron, a second steam generating passage extending in said upper section at the marginal edge portion thereof approximately throughout and having an inlet at the rear of the iron, and means establishing communication between the outlet of said rst pasin claim 2, wherein said first passage consists of interconnected V-shaped branches,
